OmniRoute License: MIT Terms, Usage Rights, and Compliance Requirements

OmniRoute is released under the MIT License, a permissive open-source license that permits commercial use, modification, and distribution provided the original copyright notice and full license text are retained with all copies.

Understanding the OmniRoute license is essential before integrating this AI routing framework into production environments. According to the source code in diegosouzapw/OmniRoute, the project applies standard MIT terms across its core codebase and all bundled extensions, with the official license text maintained in the repository's top-level LICENSE file.

MIT License Terms and Location

The definitive license for OmniRoute resides in the root LICENSE file within the repository. As of release v3.8.51, this file contains the complete MIT License text governing all code in the src/app/api/v1/, open-sse/handlers/, open-sse/services/, and src/lib/db/ directories.

The MIT License imposes minimal restrictions: you may use the software for any purpose, including commercial applications, modify the source code, distribute binaries, and even sub-license the work. The sole requirement is the preservation of the original copyright notice and the inclusion of the license text in any redistributed copies or derivative works.

License Scope Across the Monorepo

The MIT terms extend beyond the core application to all packages within the @omniroute namespace. Each bundled extension—including @omniroute/opencode-provider, @omniroute/opencode-plugin, and @omniroute/opencode-plugin-v2—maintains its own LICENSE file containing identical MIT provisions. This ensures consistent legal terms whether you are importing the main router or specific provider plugins.

Key Governance and Architecture Files

Several critical documents coexist with the license to define project standards:

• LICENSE — Contains the full MIT license text for the core project and serves as the legal authority for all usage rights.
• AGENTS.md — Defines project conventions, hard rules, and architectural guidelines that contributors must follow when modifying the codebase.
• docs/architecture/ARCHITECTURE.md — Details the layered architecture covering API routes, handlers, executors, and translators subject to the MIT terms.
• src/app/api/v1/ — Next.js App Router entry points where the publicly licensed API routes are implemented.
• open-sse/handlers/ — Core request-processing logic for chat and embeddings operations covered under the same license.
• open-sse/services/ — Routing and resilience mechanisms, including combo strategies and circuit breakers, all MIT-licensed.
• src/lib/db/ — SQLite domain modules for persistent storage, equally subject to the permissive license terms.

Practical Usage Under MIT Terms

The MIT license imposes no runtime restrictions or special licensing code requirements. Below are standard implementation patterns that respect the license terms through proper attribution in your project's documentation.

Starting the OmniRoute Server

// Start OmniRoute using the built-in CLI
// No special licensing code is required; the MIT license permits unrestricted use.
import { spawn } from "child_process";

const proc = spawn("npm", ["run", "dev"], {
  stdio: "inherit",
  env: { ...process.env, PORT: "20128" },
});

proc.on("close", (code) => {
  console.log(`OmniRoute exited with code ${code}`);
});

Integrating with the Chat Completions API

// Example: call the chat completions endpoint
async function askOmniRoute(prompt) {
  const resp = await fetch("http://localhost:20128/v1/chat/completions", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ model: "gpt-4", messages: [{ role: "user", content: prompt }] })
  });
  const data = await resp.json();
  return data.choices?.[0]?.message?.content;
}

These examples demonstrate how to interact with OmniRoute's API routes and handlers without license-enforced technical limitations.

Summary

• OmniRoute uses the MIT License located in the repository root LICENSE file, permitting unrestricted use, modification, and distribution.
• All packages in the @omniroute namespace, including provider and plugin extensions, are individually licensed under identical MIT terms.
• Commercial use is fully permitted, including incorporation into proprietary applications and sub-licensing of derivative works.
• The only compliance obligation is the retention of copyright notices and inclusion of the full license text in any redistribution of the open-sse services, src/lib/db modules, or API route implementations.

Frequently Asked Questions

What license does OmniRoute use?

OmniRoute uses the MIT License, with the full legal text available in the LICENSE file at the repository root. This permissive license allows the software to be used commercially, modified, and distributed with minimal restrictions.

Can I use OmniRoute in a commercial product?

Yes. The MIT License explicitly permits commercial use, including selling products that incorporate OmniRoute's src/app/api/v1/ routes, open-sse/handlers/, and database modules. You are not required to open-source your own code, provided you include the original copyright notice and MIT license text.

Are the @omniroute extensions covered by the same license?

Yes. According to the repository structure, bundled extensions such as @omniroute/opencode-provider, @omniroute/opencode-plugin, and @omniroute/opencode-plugin-v2 each contain their own LICENSE file applying the same standard MIT terms as the core project.

What are my compliance obligations when redistributing OmniRoute?

When redistributing OmniRoute or creating derivative works, you must include the original copyright notice and a copy of the MIT License text found in the LICENSE file. This applies whether you are distributing the full application or just the open-sse/services/ and src/lib/db/ components.
